Ignition Version 8.1.16

Just playing with the perspective sparkline component. The manual suggests that a string is a valid input for the sparkline ‘points’ property. If I put the string ‘0,20 1,35 2,15’ (copied direct from the manual) into the ‘points’ property, the sparkline doesnt appear to work. Is there a certain way it needs to be input into the ‘points’ property?

Nevermind, my mistake was the quotes… once I removed the quotes it worked.
